Recyclable: Electronic Components That Separate In Hot Water

Recyclable electronic components

It’s no secret that there is a serious waste problem within the electronics industry. That’s what inspired the latest project by the National Phyysical Laboratory, In2Tec Ltd, and Gwent Electronic Materials Ltd. The result is a printed circuit board with components that are easily separated when immersed in hot water.

From KurzwelAI:

The project partners designed, developed and tested a series of unzippable polymeric layers that allow the assemblies to be easily separated at end-of-life into their constituent parts, after immersion in hot water — while withstanding prolonged thermal cycling and damp heat stressing.

This allows as much as 90% of the original structure to be reused, compared to the 2% of traditional PCB material that can be reused.

This ReUSE project (Reuseable, Unzippable, Sustainable Electronics) is funded by the Technology Strategy Board of the UK and aims to increase the recyclability of electronic assemblies, to cut down on the 100 million electronic units discarded every year in the UK alone. With as much as 85% of waste going into landfills, this leads to around 1 million tons of e-waste just in the UK every year.

This technology is available for rigid, flexible, and 3D structures, allowing the industry to focus on new designs that will benefit from this and help reduce material waste. Do you think the electronics industry will start to use inventions such as this to curb the rapidly growing e-waste problem?
